Instead, should we change this patch to update the documentation, advising users to explicitly set computes_need_external_bridge: \"yes\" in their globals.yml when using the OVS driver with external/provider networks on compute nodes? Let me know your thoughts.","commit_id":"800e8593cab17e85dab39cfd3b0f295add794dc7"},{"author":{"_account_id":38981,"name":"seungokim","display_name":"rtd7878","email":"rtd7878@gmail.com","username":"sok","status":"I\u0027m aspiring Cloud/Infra Engineer."},"change_message_id":"cd7b369d613d8668d670342a0babe1c81bcd098c","unresolved":true,"context_lines":[{"line_number":340,"context_line":"This issue can occur even if ``neutron_external_interface`` and"},{"line_number":341,"context_line":"``neutron_bridge_name`` are correctly defined in ``globals.yml``."},{"line_number":342,"context_line":"In some scenarios, Kolla-Ansible may fail to automatically populate the"},{"line_number":343,"context_line":"``bridge_mappings`` in the ``openvswitch_agent.ini`` file."},{"line_number":344,"context_line":""},{"line_number":345,"context_line":"To resolve this, you must manually define the bridge mappings by creating"},{"line_number":346,"context_line":"a configuration override at"}],"source_content_type":"text/x-rst","patch_set":5,"id":"3abfcea1_51a0bf95","line":343,"in_reply_to":"c1a57d9d_7acb04c1","updated":"2026-04-22 07:12:46.000000000","message":"Hi Jens,\n\nFollowing up on my previous comment, I\u0027ve uploaded a new patchset. Upon further review of the Kolla-Ansible variable hierarchy, I realized that computes_need_external_bridge is an internal derived variable.\n\nTherefore, in the updated documentation, I recommended setting the standard user-facing variable enable_neutron_provider_networks: \"yes\" instead, which naturally sets the internal flag and generates the bridge_mappings correctly.\n\nPlease take a look when you have a moment.
